This graphic shows results of the first analysis of martian soil by the Chemistry and Mineralogy (CheMin) experiment on NASA's Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes, and olivine mixed with some amorphous (non-crystalline) material. The soil sample, taken from a wind-blown deposit within Gale Crater, where the rover landed, is similar to volcanic soils in Hawaii. The colors in the graphic represent the intensity of the X-rays, with red being the most intense. // Credit: NASA/JPL-Caltech/Ames
